Hi,
* I know JPCT doesn't support Orth camera (Isometric projections and bla bla ...).
I working on an Android app that allows you to manipulate (move, rotate, scale ...) a 3d model (with texture) and as you might guess when I move the objects to the coroner's it feels "tilted" .. camera perspective issues and etc..
I'm trying to figure out good FOV and Camera Distance values that a good user experience when moving to objects to the corners of the screen.
I can played with values a lot and results are hard to judge.
Any suggestion for a good "hard coded" values that will provide me with something close to a flat camera ? 
 
			
			
			
				Here is what I'm using in my VoxelShop application (desktop software renderer) @ http://blackflux.com/node/11
    public static final float SIDE_VIEW_MIN_ZOOM = 10000f;
    public static final float SIDE_VIEW_MAX_ZOOM = 60000f;
    public static final float SIDE_VIEW_ZOOM_START = 20000f;
    public static final float SIDE_VIEW_ZOOM_FOV = 0.015f;
Should give you a good starting point.
			
			
			
				My camera never moves so I assume the min/max values aren't relvant
If I understood  you correctly  the code that will get to the values you suggest:
      world.getCamera().moveCamera(Camera.CAMERA_MOVEOUT,
            SIDE_VIEW_ZOOM_START);
      world.getCamera().setFOV(SIDE_VIEW_ZOOM_FOV);
Correct ?
			
			
			
				Depending on where your objects are, yes. Also make sure you set the far plane correctly.
